这篇文章主要介绍了php多任务程序实例,需要的朋友可以参考下
本文以实例简单解析了php多任务程序的实现方法，，具体代码如下：
_pref = 0; } public static function getInstance($file) { if (null == self::$_instance) { self::$_instance = new self; } $descriptor = array( 0 => array("pipe", "r"), 1 => array("pipe", "w"), 2 => array("file", "./error-output.txt", "a"), ); self::$_instance->_pref = proc_open("php -q $file", $descriptor, self::$_instance->_pipes); return true; } public function __destruct() { proc_close($this->_pref); $this->_pref = null; } } // 测试代码 $file = __FILE__; if(empty($argv[1])) { $t2 = Thread::getInstance("$file 1"); $t3 = Thread::getInstance("$file 2"); $t4 = Thread::getInstance("$file 3"); $t5 = Thread::getInstance("$file 4"); $t5 = Thread::getInstance("$file 5"); $t5 = Thread::getInstance("$file 6"); $t2 = Thread::getInstance("$file 7"); $t3 = Thread::getInstance("$file 8"); $t4 = Thread::getInstance("$file 9"); $t5 = Thread::getInstance("$file 10"); $t5 = Thread::getInstance("$file 11"); $t5 = Thread::getInstance("$file 12"); echo "Main thread done\n"; } else { $somecontent = "\r\n//~~~~~~~~~~~~-这次请求序号是：" . $argv[1]; sleep(mt_rand(0, 3)); $handle = fopen($file, 'a+'); fwrite($handle, $somecontent); }
